SPECIFICATION forming part of Letters Patent No. 706,928, dated August 12, 1902. Application filed December 4, 1901. Serial No. 84,605. (No model.)

cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Valves for Gas-Fixtures;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel construction in a valve for gas-fixtures, the object bein g to provide a device of this character which can be mounted upon the lower end of a chandelier and control a cluster of lights, thereby bringing the valve-stem within easy reach and doing away with chains now used to 0perate the valves of such fixtures; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed. I

In the accompanyingdrawings,illustrating my invention, Figure 1 is a central longitudinal section of a valve constructed in accordance with my invention. Fig. 2 is a section of same on the line 2 2 of Fig. 1: Fig. 3 is a section similar to Fig. 2, but showing the gasinlet at one side of-thevalve-casing.

My invention is particularly designed for controlling a cluster of lights where all lights are simultaneously ignited and extinguished. Such clusters are generally mounted on the lower end of a drop-light fixture and are con trolled by a valve interposed in the fixture above the cluster and such valve operated by means of chains. This arrangement is not only clumsy, but likewise expensive and inconvenient. Each light of the cluster is fed by meansof a pipe radiating from a sphere or cylinder mounted on the lower end of the drop fixture or pipe and which is bored to feed each pipe. By making such sphere or cylinder also serve as the valve-casing, and therebydoing away with the valve and chains above the cluster,l not only save several parts, but add greatly to the convenience and appearance of the fixture.

In said drawings, A indicates the droppipe; B, the valve-casing C, the valve thereand secured at its upperend by means of the washer F and screw Gin the usual manner. The said valve is bored longitudinal from the top to form the gas-inlet H, the screw G being also bored. At its middle portion said valve is provided with a radial opening I, entering the lower end of the inlet H. The said radial opening I is adapted to register with a similar radial opening J in said casing B, leading to one of the nipples E. From said nipple passages K lead to the two nextadjacen'tnin ples and from latter to the other nipples, thus establishing communication between said opening J and all of the nipples E, thereby enabling said valve C to control all the lights of the cluster simultaneously.

In Fig. 3 I have shown my device slightly modified to adapt it to a bracket, L being the feed pipe or bracket. In this case the opening I in the valve Cis made entirely through the valve, and the opening J in the casing 13 is also made entirelythrough the latter, thereby connecting the pipe L with the outermost or diametrically opposite nipple. The latter is connected by the passages K with the re- Inaining'nipples.

My device is Very cheap and easily made and is a great saving over the construction now generally used, besides being more ornamental and convenient. Obviously the stem of the valve may be of any desired length to bring it within reach of the operator.

I claim as my invention- A fitting for gas-fixtures comprising a shell made of a single piece of metal, provided with a plurality of gas-outlets and one gas-inlet, a conical valve mountedin the center of said shell, said valve beingadapted to control the flow of gas through said fitting, and also adapted to be held to its seat by means of a screw in the small end of same, and said casing be* ing provided with a gas-passage leading from In testimony whereof I aflix my signature said gas-inlet to said valve and also with a in presence of two witnesses. passage leading from said valve to one of said outlets, also with circumferential passages 5 adapted to connect adjacent gas-outlets, to Witnesses:

the end that all of said outlets will be supplied RUDOLPH WM. LOTZ, from the passage leading from said valve. E. F. i/VILSON.
